问题描述
你好，
有这个XML的问题，我需要XSLT过滤产品列表
基于RULE标签中的规则写入。 />
我只需复制与CAT匹配的PRODUCTS-LIST中的CAT和PROD数据以及RULE标签中的
PROD ID.
for ex：

此转型：
< xsl：stylesheet version =" 1.0"
xmlns：xsl =" http：//www.w3.org/1999/XSL/Transform">
< xsl：output omit-xml-declaration =" yes" indent =" yes" />
< xsl：strip-space elements =" *" />
< xsl： template match =" ROOT">
< xsl：copy>
< xsl：apply-templates select =" PRODUCTS-LIST" />
< / xsl：copy>
< / xsl：template>
< xsl：template match ="产品 - 列表">
< xsl：copy>
< xsl：apply-templates
select =" CAT [@ ID = / * / * / * / RULE / CAT / @ ID]" />
< / xsl：copy>
< / xsl：template> ;
< xsl：template match =" CAT">
< xsl：copy-of select =
" PROD [@ID = / * / * / * / RULE / CAT
[@ID = current（）/ @ ID] / PRO / @ ID]" />
< / xsl：template>
< / xsl：stylesheet>
应用于source.xml时：
< ROOT>
< PAGE NAME ="主页" URL =" HP.html">
< RULES>
< RULE>
< CAT ID =" 1" ;>
< PRO ID =" 3">< / PRO>
< PRO ID =" 6">< / PRO> ;
< / CAT>
< CAT ID =" 3">
< PRO ID =" 2" >< / PRO>
< PRO ID =" 10">< / PRO>
< / CAT>
< / RULE>
< / RULES>
< / PAGE>
< PRODUCTS-LIST>
< CAT ID =" 1">
< PROD ID =" 12">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< PROD ID =" 6">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< PROD ID =" 3">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< / CAT>
< CAT ID =" 2">
< PROD ID =" 7">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< / CAT>
< CAT ID =" 3">
< PROD ID =" 10">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< PROD ID =" 1">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< PROD ID =" 2">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
< / CAT>
< / PRODUCTS-LIST>
< / ROOT>
产生想要的结果：
< ROOT>
< PRODUCTS-LIST>
< PROD ID =" 6">
< NAME> Prod。名称< / NAME>
< DESC> Html desc< / DESC>
< / PROD>
< PROD ID =" 3">
< NAME> ;刺。名称< / NAME>
< DESC> Html desc< / DESC>
< / PROD>
< PROD ID =" 10">
< NAME> ;刺。名称< / NAME>
< DESC> Html desc< / DESC>
< / PROD>
< PROD ID =" 2">
< NAME> ;刺。名称< / NAME>
< DESC> Html desc< / DESC>
< / PROD>
< / PRODUCTS-LIST>
< / ROOT>

感谢Dimitre ，
非常有用，最后的建议
我需要在每个CAT标签中嵌套产品 - LISTS：
< ; CAT ID =" 1">
< PROD ID =" 6">
< NAME> Prod。姓名< / NAME>
< DESC><！[CDATA [Html desc]]>< / DESC>
< / PROD>
<！ - 等等...... - >
< / CAT>
非常感谢任何帮助！
***通过Developersdex发送 http://www.developersdex.com ***
不要只是参加USENET ......获得奖励！
我在下面看不到任何产品 - 列表???也没有嵌套。

based on rules writes in RULE tag.
I need copy only CAT and PROD data in PRODUCTS-LIST that match CAT and
PROD ID''s in RULE tag.
